TONGUE FOR WHEELED SCRAPERS.

SPECIFICATION forming part 'of Letters Patent No. 556,753, dated March24, 1896.

Application filed February 20, 1895. Serial No. 589,150. (No model.) F

To all whom it may concern.-

it known that I, HENRY L. JACOBS, a citizen of the United States,residing at C- lumbus, Franklin county, and State of Ohio,

have invented a new and useful Improvement in Tongues for IVheeledScrapers, of which the following specification, taken in connection withthe accompanying drawings, is a full, clear, and exact description.

It is well known that in order to accomplish good work with two-wheeledearth-scrapers it is of the greatest importance that the course of thescraper be perfectly under control of the tongue, for the scraper-bowlis inclined to run into the earth too deep and will follow the directionof its edge, which forms the bottom of the bowl, unless prevented by arigid or unyielding tongue.

It is the object, therefore, of my present invention to produce asubstantial framework for connecting the pole or tongue to a wheeledscraper for preventing any sagging or bendin g out or line of thescraper-bowl when in use.

I will first fully describe my invention with reference to theaccompanying drawings, and afterward particularly point out the noveltyin the annexed claims.

In said drawings, Figure 1 is a perspective view of my improved tongueand frame, and Fig. 2 is a rear sectional view. perspective view of apair of my improved bow-shaped truss-bars secured together. Fig. atrepresents, in perspective, the separated truss-bars. Fig. 5 is a frontperspective view of a wheeled scraper provided with my improved trussedtongue.

1 represents the tongue or pole.

2 are the hounds or draw-bars rigidly bolted to the tongue at 3 andhaving the inclined portions 4, and the rear extensions or wings 5extending parallel to the tongue. The drawbars are formed withpivot-holes G for attachment to the wheeled scraper. 7 are drafthooksconstructed in the usual form and rigidly secured to the wings of thehounds.

My improved trusses for rigidly uniting the wings 5 of the hounds to theends 01": the pole 1 are constructed of two steel truss-bars Fig.3isa'l0 and 11 riveted together at 12, adjacent to their outer ends andformed bow-shaped so as to spread apart in the center to receive the endof the pole between them, one section or bar 10 passing over the poleand the other section or bar 11 passing under the pole. The extreme endsof the trussbars 10 and 11 are bent to form angular jaws which embracethe hounds or draw-bars. A bolt 15 passes through the center of thetrusses and tongue embraced thereby for securing them to the pole, whilebolts or rivets pass through the ends of the truss-bars for securingthem to the hounds.

I have shown in the drawings two trusses constructed exactly alike andsecured in the same manner some distance apart, but it is obvious thatinstead of constructing two separate trusses the same object could beaccomplished by employing only one truss broad enough to form a deepsocket for the pole.

IVith my improved trussed cross-frame, one section of each truss passingover and the other under the pole and securely connected together, it isimpossible to spring the hounds either up or down, and they willconsequently be held firmly in alignment.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. The trusses or cross-bars formed of two bow-shaped sections each endof each section having an angular jaw and the sections rigidly connectedtogether near their ends and spread apart in center to embrace thetongue or pole between them, substantially as described.

2. The combination of the trusses or cross bars, each cross-bar formedof two bow-shaped sections, rigidly connected together near their endsand spread apart in center to embrace the tongue or pole, with thetongue or pole and hounds of the scraper, and a bolt passing through theupper and lower section of trusses and pole to firmly bind themtogether, substantially as described.

3. The combination of a tongue and the hounds or draw-bars connectedthereto, with the truss-bars attached to the tongue at the center andconnected near their ends and formed with j aws which embrace thehounds, substantially as set forth.

4:. The combination of the tongue or pole, and the hounds or draw-barsconnected thereto, with the truss-frames comprising bowshaped barsconnected adjacent to their ends and spread in the middle to embrace thetongue to which they are rigidly secured, and formed with j aws at theirends which embrace IO and are rigidly secured to the hounds, as setforth.
